[texts]Low-angle normal faults-low differential stress at mid crustal levels - Power, W. L
A simple model for frictional slip on pre-existing faults that considers the local stress state near the fault and the effect of non-hydrostatic fluid pressures predicts that low-angle normal faulting is restricted to areas of the crust characterized by low differential stress and nearly lithostatic fluid pressures. The model considers frictional slip on a cohesionless low-angle normal fault governed by the failure criterion tau = mu sub f (sigma () sub n) =mu sub f (sigma sub n - P sub f) where...

[texts]Characterization of the Minimum Energy Path for the Reaction of Singlet Methylene with N2: The Role of Singlet Methylene in Prompt NO - Walch, Stephen P
We report calculations of the minimum energy pathways connecting CH2 N2 to diazomethane and diazirine, for the rearrangement of diazirine to diazomethane, for the dissociation of diazirine to HCN2H, and of diazomethane to CH2NN. The calculations use Complete Active Space Self-Consistent Field (CASSCF) derivative methods to characterize the stationary points and Internally Contracted Configuration Interaction (ICCI) to determine the energetics...

[texts]300 GeV Observations of Unidentified EGRET Sources. A Search for TeV Counterparts to BATSE Gamma-ray Bursts - Weekes, Trevor C
There are few things more intriguing in high energy astrophysics than the study of the highest energy particles in the universe. Where and how these particles achieve their extreme energies is of interest not only to the astrophysicist but also to the particle physicist. At GeV and TeV energies the problem is manageable since the physics is known and the acceleration processes feasible. But the energy spectrum extends to 10(exp 20)Ev and there the problem of their origin is both more difficult a...

[texts]Ways to Increase Launch Velocities of 2-Stage Gas Guns - Bogdanoff, David W.
The amount of space debris is rapidly increasing and the debris is distributed over a wide variety of orbits. Satellites, manned space vehicles and space stations will have to pay increasing attention to the dangers of impacts with space debris. Various armoring techniques (i.e., double or triple layer armor) will have to tested extensively to determine the most effective armor per unit weight. Intersecting near-earth orbits can lead to impact velocities up to 15 km/sec...

[texts]Experimental Constraints on the Stability of Clinopyroxene Magnesite in Iron Bearing Planetary Mantles: Implications for Nakhlite Formation - Martin, Audrey M.; Righter, Kevin
Carbon is present in various forms in the Earth s upper mantle (carbonate- or diamond-bearing mantle xenoliths, carbonatite magmas, CO2 emissions from volcanoes...). Moreover, there is enough carbon in chondritic material to stabilize carbonates into the mantles of Mars or Venus as well as in the Earth. However, the interactions with iron have to be constrained, because Fe is commonly thought to buffer oxygen fugacity into planetary mantles...

[texts]The Heat of Formation of HNO - Lee, Timothy J.
The HNO molecule is of interest in both combustion and atmospheric chemistry. For example, Guadagnini et al. have recently presented ab initio potential energy surfaces for the three lowest lying electronic states of HNO and then used these in examining several chemical reactions that take place in the combustion of nitrogen containing fuels and in the oxidation of atmospheric nitrogen. We have previously studied the ground state potential energy surface (i.e., stationary points along the HNO re...

[texts]The Performance of the NAS HSPs in 4Q93 - Bergeron, Robert J
During 4Q93, the National Aerospace System (NAS) C-90 delivered an average throughput of 3.626 GFLOPS while the NAS Y-MP averaged 0.678 GFLOPS. The C-90 rate was 5 greater than the previous two quarters. Reasons for the increased performance included a vector length which exceeded the 3Q value by 13 and a vector operation fraction which exceeded the 3Q value by 1. Despite the increase in vector length, insufficient vector lengths continue to hinder HSP performance...

[texts]Sulfur and carbon cycling in organic-rich marine sediments - Martens, C. S
Nearshore, continental shelf, and slope sediments are important sites of microbially mediated carbon and sulfur cycling. Marine geochemists investigated the rates and mechanisms of cycling processes in these environments by chemical distribution studies, in situ rate measurements, and steady state kinetic modeling. Pore water chemical distributions, sulfate reduction rates, and sediment water chemical fluxes were used to describe cycling on a ten year time scale in a small, rapidly depositing co...

[texts]Computational fluid dynamics research - Chandra, Suresh
The focus of research in the computational fluid dynamics (CFD) area is two fold: (1) to develop new approaches for turbulence modeling so that high speed compressible flows can be studied for applications to entry and re-entry flows; and (2) to perform research to improve CFD algorithm accuracy and efficiency for high speed flows. Research activities, faculty and student participation, publications, and financial information are outlined.

[texts]The Parent Magmas of the Cumulate Eucrites: A Mass Balance Approach - Treiman, Allan H
The cumulate eucrite meteorites are gabbros that are related to the eucrite basalt meteorites. The eucrite basalts are relatively primitive (nearly flat REE patterns with La approx. 8-30 x CI), but the parent magmas of the cumulate eucrites have been inferred as extremely evolved (La to greater than 100 x CI). This inference has been based on mineral/magma partitioning, and on mass balance considering the cumulate eucrites as adcumulates of plagioclase pigeonite only; both approaches have been c...

[texts]Performance Evaluation and Modeling Techniques for Parallel Processors - Dimpsey, Robert To
In practice, the performance evaluation of supercomputers is still substantially driven by singlepoint estimates of metrics (e.g., MFLOPS) obtained by running characteristic benchmarks or workloads. With the rapid increase in the use of time-shared multiprogramming in these systems, such measurements are clearly inadequate. This is because multiprogramming and system overhead, as well as other degradations in performance due to time varying characteristics of workloads, are not taken into accoun...
